So, what happens to the hydrogen that escapes the atmosphere? Does it get caught in the solar wind and just blow out of the solar system?
No. Mars has no magnetosphere, and hydrogen isn't typically ionized, so I'm not sure that the solar wind would necessarily push it along well unless there was a sufficient CME. Think flotsam floating in the ocean; the waves don't affect it much, but the current does. In any case it won't leave the solar system, though, because it doesn't achieve escape velocity; it won't get past the heliopause.
*hopes none of this is Googled*
So, basically, there is a shit-ton of hydrogen just kind of meandering around in the vicinity of Mars or Mars' path around the sun? Or does it tend to fall toward the sun once it escapes Mars's atmosphere? I am too lazy and ignorant to work out the mechanics, even in rough terms.
Dude, it's everywhere, even in interstellar space, just not very dense. It does get carried along by solar wind, just think of it more like a gentle breeze not a leaf blower.
Hard to believe, but there isn't much that gets pulled into the sun; besides pressure from the solar wind, which you've mentioned, things in space have an orbital velocity, and to get to the sun, you have to expend a lot of energy to slow down in order to fall to a lower orbit. There have been lots of suggestions to send garbage or nuclear waste into the sun, for instance, but it's actually easier to send it out of the solar system than it is to send it into the sun.
Huh. Fascinating. thanks for the learnin'.
Tigers fan won't return Albert Pujols' milestone ball: 'I'm not in it for the money'
Having never gotten a ball at a MLB game, let alone a milestone one, I have no idea how I would react.
Twins batting average in May - .270
Twins opponents slugging percentage in May - .269
They've clawed their way up to third in MLB in Beane Count, with unsurprisingly the # of BB drawn as the major detractor.
anybody have experience with Roomba-type robotic vacuums?
I am seeing on the Bookface a pretty breathless advert for a "new" and "better" product for under $100, allegedly built by former engineers from one of the majors. At that price point, I'm probably willing to try.
Our downstairs is mostly laminate or tile, with small mats at entries and a couple of low-profile area rugs. Lots of exposed laminate and tile. Lots of blue crystal kitty litter that gets scattered throughout the house by the damn cats. The Mrs has been resistant to getting a litter-catching mat for our laundry room (where the box lives) for some reason. And I am really tired of stepping on blue crystals everywhere.
yep -- we have one for each floor. We have a Eufy II (which we've nicknamed "Relentless") and a Eufy IIs (nicknamed "Smoov"), both were under $200 off eBay (one was used once). The IIs does a great job of not making me go rescue it, unlike the II -- it has a slightly lower profile and handles transitions better.
Neither are intelligent about where they go, but over time they cover the ground and we don't see a dust build up. You have to be aware of traps and make sure the floors are kept more or less cleared (typical items on the floor aren't a problem; cords or some clothing can be); don't use if your pets leave biological messes. You also have to be diligent about emptying the dust bins. Our vacuums run ~1hr15min and take 6hr to charge, so I have them each run once a day. They do not hurt if they bump you or the wipers hit you.
If you have rugs, they can't have tassels on the edges or that will be a problem.
Slippers seem like a less expensive solution. And who makes your cat litter, Walter White?
these guys:
It's great litter, but they do scatter crystals everywhere.
Yea, that's a great, hilarious, horrifying warning.
Hug your families and friends, folks. Life is often too short, and too weird, not to appreciate what you have from time to time.
The recaps and Minor Details will be on hiatus again, until at least Wednesday. Sunday is what it is, and then I'll be gone a couple of days for my dad's funeral.
I hope it’s a celebration of a life well lived, padre, and I hope many good memories are shared.
Dido.
Thank you. I hope it will be both a celebration of life and, also a mourning of the death. It was a life well lived, and that should be celebrated. But I also think it's important not to ignore the grieving or cut it short. Yes, he lived a long and good life, but he's still our dad, and we love him, and we're going to miss him. I think it's important to recognize both of those things.
Viva and Jerry are (were, sob) my neighbors. They are having an Estate Sale this morning. Hoping to pick up some Elvis stuff.
I hadn't heard about Jerry passing. Too bad you've lost all the weight. You would have looked great in one of Jerry's western shirts!
I hope you swing by the Cardinal after making a purchase.
Exactly. I was so bummed all the shirts were XL. I definitely would’ve picked up one or two.
They're having an estate sale for Larry Hendrickson, my neighbor growing up, today as well.
In my daily genealogy feed this morning was a familiar name
ayyup.

It's always about the money.

Well, that IS interesting. Thanks, Rhu.
